Detailed explanation-1: -The TLS and SSL protocols can be divided into two layers. The first layer consists of the application protocol and the three handshaking protocols: the handshake protocol, the change cipher spec protocol, and the alert protocol. The second layer is the record protocol.
Detailed explanation-2: -While SSL provides keyed message authentication, TLS uses the more secure Key-Hashing for Message Authentication Code (HMAC) to ensure that a record cannot be altered during transmission over an open network such as the Internet.
Detailed explanation-3: -TLS, the more modern version of SSL, is secure. What’s more, recent versions of TLS also offer performance benefits and other improvements. Not only is TLS more secure and performant, most modern web browsers no longer support SSL 2.0 and SSL 3.0.
